The NXP LPC2888 is a 16/32-bit ARM7TDMI-S CPU with 64 kB RAM, DMA, SD/MMC controller, I2C, I2S, two 32-bit timers, LCD controller, 10-bit general-purpose ADC, stereo 16-bit ADC and DACs. It can be powered by 0.9V to 1.8V, which means a single 1.5V battery cell is more than sufficient to run it.

This header board adds 32 MB SDRAM, 2 MB external Flash and a High-Speed 480 Mbps mini-USB connector. Two 60-pin extension headers give you access to all the CPU ports, and a JTAG connector is provided for programming the LPC2888.
